ec: Created lightbar params v2

The 'lightbar params' v1 command has a parameter list that exceeds 120 bytes,
which will not work over i2c. Therefore, I created a params v2 command which
breaks up the existing parameters into logical groups which are less than 120
bytes.

TEST=Tested new lightbar params2 command and ran get/sets on all groups for
samus. Repeated test on ryu as well.
BUG=chromium:467716
BRANCH=none
